Сравнительная оценка накопления каротиноидов штаммами ibss-1 и ibss-2dunaliella salina teod. в интенсивной культуре [Articol]

Abstract

The specialty of the carotenoids accumulation of the two strains of Dunaliella salina on the 2nd stage of mass cultivation were studied. During experiments the illumination of cultivators’ working surfaces was varied – 200 and 80 Watt·м-2 , as well as the temperature – 35 ° and 28 ° C, and the concentration of sea salt – 240 and 120 g ·dm-3 . It was experimentally shown that the investigated strains respond differently to the influence of stress factors, what is proved by different contents of β-carotene in the cells of microalgae. The need to take the genetic characteristics of strains into account within the selection for their industrial production was underlined.
